flame thrower any one???

[jtheshowstoppper]

was wondering if anyone know how to make a flame thrower for a mini

 

[2or3wheels]

what are you talking about? If your moving the flame will go back towards you.

 

[jtheshowstoppper]

i mean for the exhaust cause im making a custom right now for it

 

[my_mini_bike]

do you mean like a flame thrower thats shoots constant flame or just spraks/flashes coming out of a short pipe ?

 

[jtheshowstoppper]

the ones that spark with a plug and a lil fuel when reving the engine

 

[ed1380]

i think he want's flames coming out of his exhaust

 

[jtheshowstoppper]

yes what i need to know is if a plug is grounded and powered will it spark? or will i need a coil?

 

[2or3wheels]

I dont know, probly a coil because you dont want the spark for the engine to be to weak.

i'm unsure it would work -- the way that works is that you cut the ignitionso that fuel is still shooting, but no spark, and then a secondary spark plug at the end of the pipe is activated so that it will ignite the unused fuel and shoot flames.

the problem is that once you cut the ignition on a mini, you can't turn it back on without pulling the starter again. Also, when the engine dies, I don't know that enough fuel would enter the exhaust... Any more thoughts?

 

[robin]

can you just ease it off when i slow down mine back fires

 

[athif]

you know when u start your gas stove, you have that little spark that constantly tics until the gas catches fire? You can buy those at a stove repair shop or any hardware store, it will constanly give a powerfull arc shock like a sparkplug, but it wont use as muhc power, u can also buy a mini generator to power the sparkplug if u choose the sparkplug method

 

[jtheshowstoppper]

thnx never thought about that and i wasnt gonna use the same spark source as engine robert i was gonna run a whole new system in the rear behind the engine

 

[RobertD]

right, of course you need the 2nd plug, (or some source of fire) but how will you get the extra fuel into the pipe?

 

[jtheshowstoppper]

just from when i rev the engine it wont go know where (weak engine) but is should be good enough

 

[2or3wheels]

If your engine is reving eneugh you can turn the iginition b ack on and it will work, but u gotta be quick. As for the fuel i dont know.

 

[robin]

if your ading more petrol in the exhaust it wont burn becuse ther is no air in the exhaust to burn.

 

[tykenfitz]

how bout a flame thrower thats seperate but monteded on there? make an electric sparker with a 9 volt and a button frfom radio shack now for somthing to shoot the fuel i have no idea

 

[2or3wheels]

good idea, just the fuel problems.

 

[kibble]

Ummmm... fuel spurting out uncontrolled probably not a good idea. What about maybe using a fuel injector from a car? I've never played with one, although I have been wanting to. Maybe if you had one mounted spraying the inside of the exhaust pipe right before the opening and then something like the sparkplug to ignite it right after that. I'm not sure how an injector works exactly but if it's as simple as it just needing a pulse of electricity, then maybe you could just use a battery and a switch connected to it. Hmmm I'm tempted to try this now. I'll have to go by the junkyard soon and go harvest some injectors.

NICE let me know if it works.
